So. Would that be the convultaed plastic pipe that connects to side of aos when you say vac connection? 

Don't have a reader that produces live results I can clear codes and rest stuff so bit hard to get live readings

A new oas was fitted when first bought car 2.5 years ago

But it was the cheaper one d911 sell so something to think about unless someone local to me has a reader that gives live stats and would be happy to test with me otherwise I think back to porsche specliast which after the £533 mot bill this week am a bit strapped for cash at mo 

Once again Thankyou all for the input and advice I wish I was more mechinal minded but at least I can swap the maf myself

So in essence it's broke

New maf will be fitted this weekend weather permitting unless @bally4563 will let me use his garage lol and as stated before when I put secondhand maf on it August time car instantly stopped smelling of fuel and the porsche specliast I had maf off had it in stock for some time and had no idea why it was swapped so maybe I will get lucky with new maf

OK got the emissions paperwork out

Cocor 0.28

Lambda 1.643 should be 1,030

Co 0.17

Co2 8.9

Hc 89

O2 8.54

They got the fast idle emissions down but Lambda still high they are the hydrocarbon emissions and ubends have been resealed don't sound like it's sucking in as much air so going to get a new maf as opposed to secondhand and see if that makes any difference and i can drop past and they will stick the gas analyser in and see what readings are like 

At least now I got time to find a replacement although it now has a squeak on os rear sounds like a bird squaking do don't know with coffin arm being replaced both rears if something else has now failed

OK so slight rewind

Couple of months before mot I could drive to petrol station and whole car would reek of fuel and that would be a couple of mile drive after fitting secondhand maf from porsche specliast that smell instantly went away but nothing to say that maf isn't faulty? And if injectors wouldn't it run rough or am I being totally thick? 

It runs well just rich lol

OK so garage has got fast ide emissions down but hydro carbon emissions are still high but he is going to pass it but it needs work so do I get a maf? 

Arms have failed not the bolts as above bolts are seized and need to be cut off they are special as they are used to track up the car so you cant put standard bolts back in

Emissions are higher than the testing levels so even if their is too much air getting my understanding is the maf will compensate and put more fuel into mix or maybe I am talking utter nonsense as I am talking from my limited mechanical knowledge

To be fair Mick"s anology is correct I bought without any knowledge I have gained some now and 99.5% sure it will be another boxster as much as I would like a 987 realistically not an option but a 986.2 is attainable

Need to see the mot through either don't do anymore to it or yippee it's got mot then I can plan next move

And to be fair the suspension ain't the reason why Iost faith in it I think its the ongoing battle with emissions

The problem is the  idependant porche specliast in the area won't be able to look at it straight away and don't do mots

And it's a daily so not really an option to have off road for a long period  totally get the bit about big bills due to age but it's not my forever car 

Yes I love how it drives and having roof down but I also have to be realistic and having purely as a weekend car isn't an option for me either

Turns bolts are out and of stock so will be middle of next week hopefully the u bends being refitted will help with emissions and even with a mot due to bodywork it needs sorting never going to be worth a lot of money

So bolts didn't arrive so going to be next week before any progress so what if resealing u bends new lambda which garage will try next don't reduce the emissions? 

I will be into £500 by then with the new coffin Arms and 1drop link fitted I have lost faith in the car what point do I call it quits and if I go that route what's it worth as spares or repairs? 

I am thinking about £1,500

Work done in last 12months

New front struts, springs and topmounts,fuelpump, roof with glass rear window, bonnet respray, 2rear wheels refurbed, fuel pump relay, new wheel bolts rear got fronts to go on, clockspring replaced, 2 cats, Lambda probes and dansk backbox

This has come to over 3and 1/2 grand 

Not trying to be greedy but if I go that route need to pull some back to put to replacement don't have time or space to break it

Those cylinder 1,2,3 misfire codes have plagued me on and off for the 4 years that I've owned the car.

During that time, I haven't touched the plugs or the coil packs, but have changed both cats and both 02 sensors.

In general, the codes never showed up in cold winter months, but would be much more likely in hot weather.

If it's the MAF then why are the codes never thrown up for cylinders 4,5,6 but always for 1,2,3 as the MAF is common to both banks?

Strangely, I haven't had the codes at all this summer, but didn't really use the car on the odd very hot day this year.

The variocam system is specific to each bank, but an invoice from a previous owner showed that one side had been replaced and symptoms were clouds of smoke coming from somewhere, pretty much undrivable from what they said.

I have two theories to possibly explain the codes only coming from 1,2,3 and never 4,5,6.

Cylinders 1,2,3 are on the "hot side of the engine". By that I mean that air flows through the cooling vents from near side to off side, thus air that's flowing over 1,2,3 will have been pre-heated by flowing over 4,5,6.

The coil packs for 1,2,3 all use a common ground point on the engine.

Maybe completely wrong, but there is absolutely no sign of the  engine misfiring and it runs like a dream.

 

Mine defo not misfiring

I have the same emissions problem as you and an MOT failure. It has been traced back to the original back box which has leak somewhere but hard to find. Ive had to put back on a sports exhaust that I had and removed because to the drone noise problem. Due for a retest this morning hope that's it. As a matter of interest what type of back box do you have and do you have a noise problem

My back box was shot when cars were replaced so got a dansk oe box on now which was good condition but secondhand deeper sound than original but not too loud

@Cocky

New coil packs and plugs In august mate beru coils and plugs second set since I had car but first set were cheap ones off ebay and one coil pack broke and fell apart

Could be a wiring issue as code comes back after being cleared every 5/6 engine starts garage done oil and filter change as part of mot /repair work hopefully concentric bolts will arrive today and they can get coffin Arms bolted back up

They have resealed u bends and will retest emissions when they can get it off ramps

I see! Apologies. 

Nothing to apologise for

Also - how hot was your car? I mean when I did mine the fans were cutting in and out. So it was really hot. Just curious as to why the garage would say it wouldn't make a difference if it's hot? Or have I misunderstood ? 

You misunderstood they took the car for a blast and the hotter the exhaust was the higher the emissions got

Popped into garage on way to work they are going to reseal the u bends between the cats and backbox then see what emissions are like before removing one of the lambda's thanks for all the advice my limited knowledge is thinking on same lines as everyone

Thing is its not missing they are generated codes

Lambda was at 1.067 and that was best they could get

The other one was fast idle but can't remember what that was at value wise

Don't have local opc nearest would either be Wolverhampton or  Manchester Wolverhampton is mail order only for parts and would struggle to get to Manchester

I am starting to think maf

As car is stuck on ramps at garage they are doing the coffin Arms just the concentrator bolts and washers and nuts from design911 as bolts are seized in bushes and need to be cut out

Code wise pretty sure will be misfire cylinder 1 misfire cylinder2 misfire cylinder 3  which are always the same and been there since I bought car 2 and 1/2 years ago

Garage said emissions got worse the hotter they got the engine 

3rd Mot in row

My 2.5 boxster has failed on emissions but not only is it fast idle its also other emissions as well 

It had new cars and lambda probes this year from design 911

Also failed on coffin arms 

Garage is going to fit 2 new lambda's tomorrow just ordered new bolts for coffin arms from design911

Anyone got any ideas what else I may need to replace to get emissions down 

It will be up for sale once its got a mot as this is final straw for me love it yo bits but it seems to be an issue I can't solve

Oe spec back box on mine and retro fit softop with heated rear window and plenty of dings and dents even standard 16" rims 

I just try and keep it running 😂

The airbag clock spring and the indicator cancelling have nothing to do with each other,

 

Must be a pleasant coincidence  

Well well I removed the clock spring there was a broken piece of plastic on the surface of the swith mounting base where clock spring sits so maybe that was stopping the cancelling from engaging once replacement clock spring was fitted cancelling now working which ain't worked for about 12 months so defo a bonus 😂 

Just swapped clock spring I think it's been changed before as everything was loose put replacement in airbag light now goes off and indicator cancelling now works again got replacement for £45 so we'll happy
